has anyone successfully put a heatsink/fan on the back of their card? was putting something electrically conducive on the contacts behind the chip a problem? did you use grease?
I did that on my wildly o/ced vanta PCI. I put on a pentium hs using blue tack. It wasnt really good but it was enough to cool it sufficiently to run it stable at 160/190 (stock 100/125).
BTW, about a week after i did this i burnt up my vanta... oops
My sig's faster than yours, and it overclocks better too....
